Question Help with new ryzen build - not posting

[Phavmeister]

Just built a brand new rig - having some issues with it not posting on initial power on. Is this an issue of conflict between the CPU (Ryzen 5 3600, Part of AMDs new lineup) and the motherboard (msi b450 gaming pro canon ac)? testing it with 16gb of tridentZ 3200 and onboard graphics. I bought the parts thinking there would be no issue between mobo and cpu because amd said there wouldn’t, and said that if there were issues it would potentially need a BIOS update l, this thing won’t even post.

My second theory is that it’s because of the new 3000 series power draw. We are using 8 out of the 12 pin CPU power because the psu didn’t come with extra cables to fit all 12 slots.

There is no onboard graphics with ryzen 3600.

You will need a descrete gpu to get any post.

We have also tested the completed build including the graphics card. Could it not be posting because the B450 mobo needs a bios update to be compatible with 3xxx series CPUs?

Yea you would need the bios update.
Only the 8 pin is needed to boot.

Your board has this feature "

• Flash BIOS Button: Simply use a USB key to flash any BIOS within seconds, without installing a CPU, memory or graphics card.

"
I would try this. Instructions are in your owners manual.

Thank you, flashing the newest BIOS update worked.
